1. A method in computer graphics and computational geometry that represents a 3D solid object by defining only its surface boundaries rather than its volume
The CAD software uses boundary representation to model the exterior surfaces of the mechanical part.
O software CAD utiliza representação de fronteira para modelar as superfícies exteriores da peça mecânica.
2. A data structure that stores information about the edges, vertices, and faces that form the boundary of a geometric object
In computational geometry, boundary representation is more memory-efficient than volumetric representation for certain applications.
Em geometria computacional, a representação de fronteira é mais eficiente em memória do que a representação volumétrica para certas aplicações.
